Narrative:

The flight crew and passengers began smelling smoke in the cabin. It smelled like an electrical fire; however the first officer (first officer) heard what sounded like a seizing bearing from pack 2 (the only pack that was running at the time) and the ca (captain) reached up and quickly turned off the pack. The first officer ran out to check to see if the pack was actively on fire. It was not; from the first officer's perspective. The ca turned around and saw smoke in the cabin and immediately commanded the flight attendant (flight attendant) to evacuate the aircraft as we were still at the gate and the main cabin door was open. The flight attendant got the passengers off the plane with the assistance of the ca and first officer. The ca called operations to call the arff (airport rescue and fire fighting) as there was smoke. Maintenance was also called to the plane. The aircraft was deemed fire safe by arff captain and the passengers returned to the plane to gather their personal belongings. We went to the clinic to be checked out for smoke inhalation and were told to not return to flying duty until the following day. The flight was aircraft swapped and re-crewed and departed 4 hours late.the threat was the mechanical malfunction of the air conditioning pack and the subsequent fire and smoke that caused smoke in the cabin. This led to determination by the ca to execute an emergency evacuation. I feel like we handled this issue properly. We turned off the pack and stopped the burning of it and got the people off the airplane and breathing fresh air in a very quick manner.
